Mouse position (dx/dy,dcx,dcy) reset to 0 with a wheel event about python-tcod HOT 4 CLOSED

The regression is fixed in 8.4.1 and in libtcod. Mouse wheel events in libtcodpy are now back to their usual undefined behavior of preserving coordinates from previous mouse events.

This isn't a bug, SDL2 doesn't return the mouse position on a mouse wheel event (but it does on a wheel click.)

The tcod.sys_check_for_event returns the events type, this should be used instead of giving it a partial event mask, like in the following example:

def handle_events(events):
    key = tcod.Key()
    mouse = tcod.Mouse()
    while True:
        ev = tcod.sys_check_for_event(tcod.EVENT_ANY, key, mouse)
        if not ev:
            break
        if ev & tcod.EVENT_KEY_PRESS:
            if key.vk == tcod.KEY_ESCAPE:
                raise SystemExit()
        if ev & tcod.EVENT_MOUSE_MOVE:
            print(mouse.cx,mouse.cy,mouse.x,mouse.y)

Actually, I might have been too quick to judge this. This could a regression in behavior, since mouse wheel events are put into TCOD_EVENT_MOUSE_PRESS for some reason.

Perfect, thanks !
